JOURNAL FREE ACCESSThe purpose of this study was to evaluate of usefulness of Virtual Colonoscopy (VC) fordetection of colorectal neoplasms. Helical CT was acquired using 5mm slices in width. Fortysix patients underwent VC, and colonoscopy as the gold standard after VC under informedconsent. As a results of this prospective study, sensitivity of VC was 56.8%, specificity was80.8%, and accuracy was 66.7%. In lesions over 5mm in maximum length which is the samewidth of scan slice, the diagnostic value was improved as follows; sensitivity was 81.3%, specificity was 97.1%, and accuracy was 92%. ln conclusion, VC was thought to be useful forscreening of colorectal neoplasms.View full abstractDownload PDF (7341K) -

JOURNAL FREE ACCESSA 20-years-old-man, who had suffered from Crohn's disease in the large intestine, wasadmitted to our hospital because of abdominal pain, fever, dysphagia, and chest pain onswalloviring. Upper gastrointestinal endoscopic examination revealed punched-out ulcers alongthe whole esophagus and the bamboo-like appearance in the upper body of the stomach. Non-caseating granulomas were detected in the biopsy specimens from these lesions. Therapy withproton pump inhibitor relieved dysphagia and chest pain, and the following therapy withelemental diet and mesalazine improved esophageal ulcers.View full abstractDownload PDF (10487K) -

JOURNAL FREE ACCESSWe reported a case of endoscopicaly resected early carcinoma in the Barrett's esophagus.A 72-year-Old man complaing of epigastralgia visited to our hospital. Endoscopic examinationshowed O'-Ila+Ilc type flat elevated lesion about 15mm in diameter at the esophago-gastricjunction. Biopsy specimens revealed tubular adenocarcinoma. Moreover, endoscopic pictureshowed Barrett's'Esophagus of which size was less than 3.0cm in width. Therefore, weconsidered that the lesion was esophageal adenocarcinoma arised from the short segmentBarrett's Esophagus. We performed endoscopic mucosal reSection. Pathological findingsshowed that it was early adenocarcinoma (well differentiated tubular adenocarcinoma) originat-ed from Barrett's esophagus and it was limited in the mucosal layer. Cases of endoscopicaly resected early Barrett carcinoma had been rarely reported in Japan, because most of the esophageal cancers were squamous cell carcinomas. Barrett's esophagusand Barrett's carcinoma are popular in Western countries. Westernization of diet and life styleamong Japanese people would have increased the incidence of Barrett's esophagus and Barrett'scarcmoma.View full abstractDownload PDF (8401K) -

JOURNAL FREE ACCESSA 53-year-old male with a past history of pharyngeal cancer was visited our outpatient department for screening of the upper gastrointestinal tract. Upper gastrointestinal X-ray and endoscopic examinations showed a solitary pedunculated polyp with the appearance like brain gyri in the duodenal bulb. Endoscopic polypectomy was performed using a double-channel endoscope. The resected specimen was 16×12×6mm in size and histologically revealed a branching framework of the muscularis mucosae that accompanied by hyperplastic glandular epithelium. However, neither family history of gastrointestinal polyposis nor muco-cutaneous pigmentation was observed. No hamartomatous polyps exist in other sites of the gastrointesti-nal tract. The endoscopic examination done 8 years and 10 months earlier showed no lesions in the duodenal bulb. The lesion was diagnosed as a solitary Peutz-Jeghers type polyp, of the duodenum occurring and developing during this period.View full abstractDownload PDF (7794K) -

JOURNAL FREE ACCESSA 69-year-old male was admitted to our hospital with a complaint of dyspnea on exertion due to severe anemia. An upper GI endoscopy revealed that a large tumor occupied in the second portion of the duodenum. The tumor lacked regular surface mucosal structure, showing irregular ulcerations. Pancreaticoduodenectomy was performed. Histopathologically, atypical spindle-shaped cells with severe mitotic figures were invaded from the muscle layer to the duodenal mucosa with ulcer formation. Immunohistochemical examination showed that the tumor cells were positive for a-smooth muscle actin, but negative for c-kit and CD34. We report a case of leiomyosarcoma in the duodenum with notable endoscopic feature, referring to the importance of immunohistochemical analyses on gastrointestinal mesenchymal tumor (GIRT).View full abstractDownload PDF (7476K) -

JOURNAL FREE ACCESSWe report a case of mucosa associated lymphoid tissue (MALT) lymphoma in the colon and rectum. The patient was a 46-year-old woman who was admitted to our hospital because of occult blood in the stool. Barium enema study showed flat elevated lesions in the cecam and lower rectum. Both lesions were 5×5 mm in diameter. On colonoscopic observation, tumors showed a glossy yellowish-white surface with central depression. Endoscopic mucosal resection (EMR) was performed for the purpose of diagnosis and treatment. The histopathology of resected specimens demonstrated medium sized lymphocytes with cleaved nuclei and invasion of abnormal lymphocytes into the epithelium. The abnormal lymphocytes were positive for L-26 and negative for UCHL-1 on immunological study. The patient was diagnosed as low-grade MALT lymphoma in the colon and rectum, and the depth of invasion of abnormal lymphocytes was estimated to submucosal layer. MALT lymphoma in the colon and rectum is rare. The prognosis for MALT lymphoma in the colon and rectum is good by treating adequate operation, but a standard treatment has not been established. The surgical tumor resection including EMR is done to treatment for MALT lymphoma at present. Furthermore, investigation of the long term prognosis is necessary.View full abstractDownload PDF (10733K) -

JOURNAL FREE ACCESSExpandable metallic stent (EMS) is widely used technique for the management of eso-phageal cancer and bile duct obstruction. However, the reports on EMS placement for malignant rectal stenosis were rare. We performed EMS placement for malignant rectal stenosis caused by Schnitzler's metastasis. A 45-year-old woman, who had suffered from stage IVb stomach cancer, had been treated with chemotherapy. She visited to our hospital because of abdominal fullness, nausea and vomiting. Barium enema and colonoscopy revealed marked stenosis in the rectum. We diagnosed the lesion as malignant rectal stenosis caused by Schnitzler's metastasis, and EMS were performed. After EMS placement (UltraflexTM, Microvasive, Boston Scientific Corpora-tion, MA, USA), the patient recovered to control flatulence and defecation by herself perfectly. Neither bleeding nor tenesmus had occurred. Following up for three months, stent patency and relief of bowel obstruction were shown. In conclusion, EMS is technically safe, and useful therapy for rectal malignant stenosis.View full abstractDownload PDF (5673K) -

JOURNAL FREE ACCESSA 56-year-old man had been found to have liver dysfunction at a routine health check-up. He was referred to our hospital. Ultrasonography, CT and MRI images revealed multiple SOLs in both lobes of the liver, but the final diagnosis has not been made yet. Abdominal angiography showed neither a peripheral stain nor cotton wool appearance. On laparoscopic examination these tumors were dark purple and elastic soft. The histological findings taken from the tumor disclosed numerous vascular spaces lined by bizarre endothelial cells. The tumor cells were positive for factor VIII-related antigen. These findings suggest that laparoscopic examination is useful for the diagnosis of hepatic angiosarcoma.View full abstractDownload PDF (12416K)
